BLUEFIN TUNA: Sushi chefs in Tokyo, Japan, work behind a refrigerated, counter-top display of three different types of fillets from Atlantic bluefin tuna. At the 175-nation Convention on the International Trade in Endangered Species (CITES) convention, which is underway in Qatar, the group is looking to ban the trade of Atlantic bluefin tuna. Environmentalists say that the tuna are being fished at an unsustainable rate. Japan has said it will not comply with such a ban and that it has China's support in opposing it.
